You can check the Raid consistency in Raid controller BIOS - you should be able to enter the BIOS while your motherboard starts.

Can you check system booting also without Ethernet cable inserted to NIC ?

I recomend updating to the latest version 1.37, you must register product on www.open-e.com in "service and support" section so you will have possibility to download ISO update for your module. Then you will be able to use IDE or USB CD/DVD to update the module.
